INSTRUMENT FOR INSERTING CONTINUOUS BATS INTO UPHOLSTEBY P LAITS.

Application filed February 16, 1926. Serial No. 88,626.

or more sections or longitudinally splitv parts, between which thebatting is threaded or drawn; when the operator uses such tools he isobliged to press the sections together, otherwise the continuous battingwhich is threaded through the instrument will pull out of the instrumentwhen piping the plait of the cushion which causes the batting on theinside of the instrument to wrinkle the full length thereof and when theinstrument is withdrawn the inserted batting does not fill the lait onaccount of the wrinkled condition. f the operator can not pound or pullthe wrinkle out of the cotton batting in the plait, the cottonwill haveto be taken out of the lait which means extra cost and loss of prouction. My invention, therefore, seeks to avoid these objectionalfeatures and to that end I have produced the instrument comprising thesubject matter of this invention.

Generically the invention comprises a long tubular body of proper crosssectional shape and of uniform cross section throughout that portion ofits length which is insertable in the plait, the entrant end beingprovided, with a flare or funnel-like portion, while the exit end hasprovision for an operator to press his fingers or thumb on the bat tohold it while withdrawing the instrument; the instrument is alsoprovided with bat grippers adjacent each end for the purpose of drawingthe bat from the roll in which it'is wound (or from any other source)and for the purpose of holding the but while being severed,respectively. I

'More specifically the invention also lies in those novel combinationsand arrangements of parts which will be hereinafter described andpointed out in the appended claims, reference being had to theaccompanying drawings, in which Figure 1 is a side elevation showing theinvention in use.

Figure 2 is a plan view of the same.

Figure 3 is an enlarged vertical longitudinal section of the instrument.parts being broken away showing in 11111 lines the bat gripper at theentrant end in operation.

Figure 4 is a view similar to Figure 3.

showing the bat gripper at the exit end in operation.

Figure 5 is an end elevation looking at the entraift end.

Figure 6 is an end elevation looking at the exit end.

In the drawings, in which like numerals of reference indicate like partsin all the figures, 1 is the table on which the upholstery to be stuffedis laidand on which the exit end of the instrument that constitutes myinvention may rest. 2 is the stand on which the roll-3 of continuous batis located for purposes of unwinding.

4 is the instrument which constitutes thesubject matter of my presentinvention. The instrument 4 consists of a section of tube or pipe ofuniform cross section throughout that portion of its length which isadapted to be inserted into the plaits ofthe upholstery. At the entrantend thetube 4 has a flared or funnel-like port-ion 5 to facilitate theintroduction of the bat and it is also slotted on the top as at 6 tocooperate with the bat gri per that serves to aid in un winding theliatfrom the roll 3. The gripper consists of a leaf spring 7 of a width topass through the slots 6, one end 8 of the spring 7 being secured to thetube 4 by spot welding. brazing or in any other suitable way. The frontend of the spring 7 is bent at right angles upwardly as at- 9 and thenback upon itself as at 10 to constitute a convenient means by which thegripper 7 may be depressed into the slot 6'to grip the bat. as shown inFigure 1.

The front end 11 of the tube 4 is recessed top and bottom as at 15 and16 respectively and the top is slotted as at 12 from the recess'inwardly a suitab'e distance. Lying over the slot 12 is a leaf spring13, one end 14 of which is spot welded, brazed or otherwise permanentlysecured to the table 1. Normally the springs 7 and 13 lie parallel withtheir respective slots but do not project into the inner diameter of thetube.

17 is an eye secured to the entrant end of the tube by which it maybesuspended with a cable 18 from a suitable support 19 whereby the weightof the instrument is taken oil of the operator.

20 is the plaited upholstery to be stuiied. In using my invention theroll of continuous hat 3 is placedon the unwinding stand- 2 and has itsend threaded through the in strument so that the end of the batwillproject beyond the end of the spring 13 in order that when theinstrument-is inserted its full limit into the bat the operator canpress his. thumb on the plaiting adjacent the recessed or incut parts 16and and hold the end of the bat while the tool is being withdrawn.

Before inserting the instrument into the plait pocket the operatorgrasps the instrument'adj acent the entrant end with his hand over theprojection 10 of the gripper 7 and closes down on the grip r whichforces it to the position shown in igure 1' and causes the bat to befirmly held there. Then as the instrument is advanced into the pocketthe bat is unrolled correspondingly. In withdrawing the instrument fromthe pocket the operator, of course, releases pressure on the projection10which permits the gripper 7 to restore itself to the inoperativeposition,

see Figure 4. As soon as the instrument has been withdrawn from theplait pocket the operator presses h1s thumb on the end of the springgripper 13, thereby gripping the bat adjacent the exit end 11 of theinstrument and by raising up on the instrument and holding down on theplait the section ofv the bat within the plait .is severed from the re-vmainder and the'instrument will then be sectional type 7 ready forinsertion into the next plait pocket without wrinkling or twisting thebatting.

from its normal state. The cross sectional shape of the instrument andits width and depth within, corresponds to the external shape anddimension of the bat and therefore the bat is not pressedor wrinkled aswith instruments of the longitudinal split hereinbefore referred to. iFrom the foreg'oing description, taken in connection with theaccompanying drawings,

it is thought the construction, operation and advantages of theinvention will be clear to those skilled in the art to which it relates.
